Normal daily drone...

In 1930, (Harry) Sinclair Lewis, became the first American writer to win the Nobel Prize for Literature. He said his inspiration as a writer came from, "sitting in Pullman smoking cars, in a Minnesota village, on a Vermont farm, in a hotel in Kansas City or Savannah, listening to the normal daily drone of what are to me the most fascinating and exotic people in the world — the Average Citizens of the United States."
